Description Jonathan Liu 2007-01-03 13:30:13 UTC 
When reading information from DVDs using dvdbackup, the CheckSizeArray() function may give a floating point division by zero exception as a result of failing to check if the divisor is non-zero before diving by the divisor.

How-To-Repeat: dvdbackup -i /dev/acd0 -I
 where /dev/acd0 is the DVD device

Note: This only occurs on some DVDs.
